Housing Bubble

DEFINITION of 'Housing Bubble'

A run-up in housing prices fueled by demand, speculation and the belief that recent history is an infallible forecast of the future. Housing bubbles usually start with an increase in demand (a shift to the right in the demand curve), in the face of limited supply which takes a relatively long period of time to replenish and increase. Speculators enter the market, believing that profits can be made through short-term buying and selling. This further drives demand. At some point, demand decreases (a shift to the left in the demand curve), or stagnates at the same time supply increases, resulting in a sharp drop in prices - and the bubble bursts.

INVESTOPEDIA EXPLAINS 'Housing Bubble'

Traditionally, housing markets are not as prone to bubbles as other financial markets due to large transaction and carrying costs associated with owning a house. However, a combination of very low interest rates and a loosening of credit underwriting standards can bring borrowers into the market, fueling demand. A rise in interest rates and a tightening of credit standards can lessen demand, causing a housing bubble to burst. Other general economic and demographic trends can also fuel and burst a housing bubble.
